Starfish have an endoskeleton comprised of many little bones.
Since the term starfish encompasses a whole host of different creatures with different numbers of arms, I presume the answer isn't well defined. All the skeletons I've seen have a huge number of intricate bones, but I haven't seen that many.
Term bones doesn't 'easily' apply to the phylum echinodermata. What solid spines and plates they have are part of their skin, and what gives their bodies their rigidity is a 'water vascular system' or a Hydro-skeleton' or a 'pneumatic skeleton', which depends on water pressure to make it function.
a starfish is missing a few body parts like fins and tails
Yes, they have feet and mouths!
They don't.
They can regenerate body parts
starfish sponges sea cucumber others
Most likely 5
Certain animals have their body parts arranged around a central point. A starfish is a good example of this, which is known as radial symmetry.

Fragmentation is the ability to regrow body parts...like with a starfish, or worm. Only the worm will grow two butts, so the second half will die. But with the starfish as long as you cut through part of the nucleus (Middle) it will regrow the missing parts.
These creatures are most likely starfish. Starfish have the ability to regenerate lost body parts, including their arms, which allows them to reproduce asexually through fragmentation. If a starfish is cut into pieces, each piece has the potential to grow into a new individual.
it look like a star but can swim and looks very Polk a dotty.
starfish have bumps and spines on their body
